I’m getting a HTTP Error 500 after activating the Cache Enabler plugin. Nginx logs show the following error:
PHP message: PHP Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0
I read about conflicts with Autoptimize and other minification plugins causing this problem, but I’ve tried disabling all other plugins, but even Cache Enabler alone still gives me this error. I used WP Super Cache + Autoptimize before attempting to switch to Cache Enabler. Any clues as to what may be causing this?
One more note: before getting this error, the plugin didn’t work either but gave a different error that I managed to resolve. It didn’t have permission to write in the wp-content/cache folder, but (unlike other plugins) it didn’t point out that problem in the settings. Perhaps such a check could be added?
